An e-mail ibe encryption system for owa

Abstract

The invention relates to an OWA email IBE encryption system using a pseudo-RSA digital certificate. The system includes an OWA client, a pseudo-RSA digital certificate, an IBE cryptographic module, a pseudo-RSA digital certificate issuing tool or system, an Exchange server, an AD server, The IBE public key acquisition agent and the IBE key server, wherein the IBE public key acquisition agent is an HTTP proxy or plug-in deployed or inserted into the HTTP transmission channel between the OWA client and the Exchange server, and the HTTP proxy or plug-in intercepts the OWA The client obtains the request for the encrypted digital certificate public key of the sender and receiver of the encrypted mail from the AD server through Exchange, and generates or returns the fake RSA digital certificate or fake RSA public key of the mail sender and receiver, thereby realizing OWA-based email IBE encryption reduces and simplifies the manual operations involved in the application of pseudo-RSA digital certificates in OWA.

Description

technical field [0001] The invention belongs to the technical field of information security, in particular to an email IBE (Identity Based Encryption, identity-based encryption) encryption system for Outlook webpage access (Outlook Web Access, OWA), which makes the OWA system that does not support IBE encryption An email encryption system that can implement IBE encryption of emails without modification. Background technique [0002] The current encryption algorithm can be divided into two systems: symmetric key encryption (Symmetric key Cryptography) and asymmetric key encryption (Asymmetric Key Cryptography); correspondingly, encryption technology is divided into symmetric key encryption technology and asymmetric key encryption technology . In the symmetric key encryption algorithm (technology), data encryption and decryption use the same key; in the asymmetric key encryption algorithm (technology), data encryption and decryption use two different but interrelated keys (a ...

AI Technical Summary

Problems solved by technology

[0030] The purpose of the present invention is for false RSA key and false RSA digital certificate technology to exist in OWA e-mail IBE encryption application, need manually disposing the false RSA encrypted digital certificate in the AD account, can not send encrypted mail before the recipient completes configuration and Ease of use and availability of encrypted emails can only be sent between AD domain users, and an email IBE encryption system for OWA is proposed
